It would be faster, but this would still cause the compiler to open and start parsing the file unnecessarily (possibly multiple times from multiple included files).
Another approach would be to have a pragma that means: "just don't bother including this file again if you see it", and have the compiler remember it. Perhaps there is - its a long time since I programmed in C.
